The ovals display the type of correlation direction, but there are no significance asterisks included for the correlations.
This initial version seems to busy with the large vs. small font sizes and red lines.
This correlation matrix is missing the lines from the scatterplots, but it is cleaner visually with some overlap in x-axis labels.
The color is more easily changed via the pairs.panels function.
